Herbert was only a three star recruit, dual threat QB coming out of Sheldon High School class of 2016. Mills was a five star recruit out of Norcross Georgia ranked #1 QB in the nation 2017. Per Rivals.
Davis Mills suffered from early injuries that impacted his career @ Stanford greatly. But since has fully recovered and athletically stronger than ever. Now does he get me as excited as watching Herbert, no. To me he lacks arm strength, size and has been mentioned, because of injuries, experience against top flight competition. But I do think he can command the huddle and be excellent system QB, like a Ryan Fitzpatrick. If he develops as planned has starter potential, and plus back-up if they take a #1 next year. You need at least two quality QB’s on your roster, even if you have one that’s a superstar. There will always be a market and trade value for one in the NFL.
